An assessment of IGT's experimental data on fluidized-bed coal gasification at pressures in the range of 100-450 psig was conducted by Foster Wheeler, in conjunction with the City University of New York (CUNY) as a subcontractor. The objective of this study was to evaluate the quality, reliability, and usefulness of IGT's data which was obtained in an eight inch diameter gasifier PDU. Foster Wheeler's effort focused on the results if IGT's Phase-2 test program in which fifteen steady state tests were conducted on Illinois No. 6 bituminous coal, Montana Rosebud subbituminous coal and North Dakota lignite. The scope of this analysis included an independent check on the reported study state conditions and overall balances, as well as correlating the data relative to gas phase equilibrium and the effects of operating parameters. The results of Foster Wheeler's assessment are summarized in Volume-1 of this report. 4 refs., 13 figs., 16 tabs.
